Processes That Form Minerals

• the minerals that people are using today have and still are forming deep in Earth's crust on the surface for billions of years.
  • there are two ways for minerals to form one way is through crystallization of melted materials, or through crystallization of materials that have dissolved in water.
• crystallization is the process when atoms are arranged to make a material with a crystal shape.

Minerals From Magma

• when the liquids cool to the firm state, they start to form crystals.
  • the size of the crystals depends on three types of factors.
• the rate when the magma.
  • the slower the magma cools the bigger the crystals are.

minerals form hot water solutions

• there are many solutions.
  • veins help water rise.
• a lot of minerals form.

minerals formed by evaporation

• lots of salt crystals form with dried up salt lakes.
  • the salt can also make fertilizer.

where minerals are found

• minerals can be found all over the world.
  • gold can be found near the Nevada mountains.
